[@MTBKAYDA]

Hi, can I ask what's the formula in getting the original volume when dealing with liquids?

[@ramich.x]

In the "area" question you calculated the differences of lenght and width separately and multiplied the new lenght and width to get the expanded area, and in the volume question you calculated only the difference in the volume. Which way is correct? It does not give out the same answer unless you multiply the ◇V by 3 for volume (or multiply by 2 for area)

[@LiyemaStinise]

In the first question isn't the change in temperature +75 because they said it was increased by 75 hence final temperature would be 95

[@eliasfattah1660]

it says (increased to) not (increased by)

[@odongodiana]

Why is that aswer different when you convert the temperature to Kelvin before starting to calculate

[@bweeeeniee1131]

Shouldn't you be using the units intended for the formula?

[@hannaliknaw8682]

Ur supposed to change each value into Kelvin then subtract them

An iron ring 1.20 m diameter is to be put on a wooden cart wheel. The diameter of this wheel is 1.0 cm greater than that of the ring. The temperature of the ring that must be raised before it slips on the wooden wheel is (coefficient of linear expansion of iron is 12×10−6/oC)? I need your help

Why?

[@nursechiomambamara9702]

sir I thought you will change the temperature to the standard unit use to solve which is Kelvin or am I lost

[@stanwellmtonga5103]

Nice one ❤️

[@spenceregan3509]

When calculating change in area and change in volume we were taught to multiply the Coefficient values by 2 for area and 3 for volume....is this accurate?

[@thecherrythatkakyoinverbal8931]

Yes, it's gamma(volume) = 3(alpha) and in case of water, the coefficient is always 3alpha because length and breadth of water can even be the room in which it's put. Thus, it's gamma (which is equal to three times alpha)

It's the temperature of the object which is typically atmospheric temperature unless you went out of your way to heat/cool the object.
